Royal Oak — The owner of a Troy-based automotive supplier has given one of the largest-ever gifts to his alma mater, Shrine Catholic High School, boosting the parish’s capital campaign to more than $5.3 million.

Steve Doman, chairman, CEO and owner of Empire Electronics, Inc., recently committed a “significant seven-figure gift” to the parish’s Fulfilling Our Commitment, Renewing Our Mission campaign, which seeks to raise money for various operational purposes for the National Shrine of the Little Flower Basilica and its parish schools.

Doman said the gift was a testament to the quality education he received at Shrine, which he said helped propel his life and career.

“My time at Shrine gave me a solid foundation that helped prepare me for my career,” Doman said. “I’m convinced that had it not been for Shrine, I wouldn’t be where I am now and for that I am very grateful.”

While a portion of Doman’s gift will be endowed, a portion will be used immediately to help boost enrollment at Shrine High School by offering more financial assistance to low-income families, merit-based scholarships for student leaders and increasing funds for marketing efforts and capital projects.

“Steve Doman’s gift was made because of his belief in the power of an education received from Shrine and the effect the school and community has had on his life,” said Fr. Robert Fisher, rector of the basilica.

Doman, a 1979 graduate of Shrine, played three sports and served as freshman class president during his time there. He earned degrees in accountancy and business administration from Wayne State University and the University of Detroit before joining Empire Electronics Inc., which manufactures wiring harnesses, lighting sockets, molded and overmolded electrical assemblies and electronic L.E.D. assemblies for the automobile industry, in 1989.

Shrine’s Fulfilling Our Commitment, Renewing Our Mission campaign seeks to raise money for four main objectives: debt repayment, school infrastructure repairs, parish-based religious education and school financial aid, and the eventual building of a parish center.
